Shingles is a re-awakening of the chicken pox virus. Chicken pox is on the herpes family, once you have chicken pox it stays with you forever but usually doesn't flare up again. It is said stress, illness or injury can cause the chicken pox virus to re-awaken. The virus awakens in the nerves, and whatever part of the body those nerves lead to is where the shingles will appear. They will not spread. They look like really bad acne abbesses or blisters and they hurt. I cannot describe how painful they are. Zyclovir (not sure on spelling) an anti-viral med, can help lessen the severity of the outbreak. It can last a few days to several weeks. Pain meds and hot water/vinegar compresses can help with the pain. My doctor prescribed oxycontin, but to be honest the meds didn't help the pain much. I was also on steroid eye drops (I had shingles on the left side of my face, including my eye, the drops were to prevent cornea scarring).
I asked about the risks of sterility and contagiousness , and was told I had nothing to worry about.
I have light scarring on my face, plus some nerve damage––numb areas on my forehead ––and a droopy eyelid. Hope the recovery is quick. In all honesty, if not for my kids, if I got shingles again I'd probably eat a bullet, it was that freaking bad an experience.
